Title: A process for separating a c-hydrocarbon mixture containing paraffinic,monoolefinic and diolefinic c-hydrocarbons
IPC: C07C7/08
Filed: 1963-12-23
Abstract: <PICT:1072200/C4-C5/1> A C5 hydrogen fraction is separated into paraffinic, mono-olefinic and di-olefinic fractions by feeding to the middle portion (1) of an extractive distillation column (A), feeding N-methylpyrrolidone (2) as solvent to the top of the column, removing paraffins overhead, withdrawing a liquid side stream (3) from the lower portion of the upper half of the column, separating mono-olefines from the solvent which is returned (7) at a point below the liquid withdrawal point, effecting partial condensation (5) of hydrocarbons above this feedback point to maintain the solvent to hydrocarbon ratio approximately constant throughout the column, withdrawing diolefins as vapour (8) from the lower portion of the column and returning solvent from the sump to the head. The liquid in line 3 may be distilled in column B returning overheads to the column by line 4 and recovering olefines as vapour (6) near the sump and solvent (7) from the sump or may first be separated into a hydrocarbon layer, mostly paraffins which is returned at a lower point to the column, e.g. by line 7, and a solvent layer which is distilled in column B to recover olefines.  The solvent is preferably distilled in column C before recycle to remove residual hydrocarbons by line 10.

Abstract: 1358085 Rocket combustion chambers - propellant injectors MESSERSCHMITTBOLKOW-BLOHM GmbH 8 Nov 1971 [28 Nov 1970] 51835/71 Headings F1J and F1L The forward end of a rocket combustion chamber carries a mushroom shape propellant distributor 1 on which swirl blades 2 are mounted, hypergolic propellant components (viz. oxygen and fuel) being supplied via coaxial ducts at 4 and 5 respectively, in such a way that the oxygen 4 reaches the base of the channels between the blades 2 before the fuel 5 and moistens the base, thus producing a cooling effect. The fuel 5 is applied to the film of oxygen which cools the distributor 1, and the propellant components 4, 5 react within the channels. The blades 2 are curved in such a way that a zone of reduced pressure forms on the convex side of each of the blades, the propellant vaporizing more readily in these zones and the reaction is thus enhanced. In order to intensify the reaction in the reduced pressure zones and to supply them with fresh propellant, apertures a are provided through the blades 2 at the base of the zones.

Abstract: 1446938 Automatic control of speed SONY CORP 8 Nov 1973 [11 Nov 1972] 51887/73 Heading G3R A video tape recorder is provided with an adjustable delay circuit in the circuit used to control the head wheel speed on playback whereby the trailing of the heads can be adjusted so that tapes recorded on other machines can be replayed satisfactorily. The arrangement shown provides a normal recording circuit where the speed of the headwheel 2 is controlled by brake 9 in accordance with a comparison in comparator 21 of the actual speed detected by pick-off 13c and the desired speed signal which is the vertical sync. signal derived from the incoming video signal at point 16. The sync. signal also is applied to recording head 14 to record a control signal on the tape. For playback the switches 15c, 15d, 15e are switched to the P position so that comparator 21 now compares the head speed signal from pick-off 13c with the replayed control signal from head 14 and produces the brake control signal. If however the reproduced picture quality is poor indicating that heads 2 are not accurately aligned with the record track a switch 22 can be charged over to provide an actual head speed input to comparator 21 from pick-off 13b through monostable multivibrator 23 whose dwell time can be manually adjusted so that the actual speed signal is delayed by an adjustable amount to effectively charge the head speed until the individual heads scan the recorded track on the tape.
